To scale out the AWS resources using manual AutoScaling, which of the below mentioned parameters should the user change?
Current capacity
Desired capacity
Preferred capacity
Maximum capacity
Explanations:
Current capacity represents the number of instances currently running. It cannot be directly changed; it reflects the current state of the Auto Scaling group.
Desired capacity is the target number of instances you want in your Auto Scaling group. By changing this value, you can manually scale out your resources.
Preferred capacity is not a standard term in AWS Auto Scaling. Users typically deal with desired, minimum, and maximum capacities instead.
Maximum capacity sets an upper limit on the number of instances in the Auto Scaling group, but changing this value does not directly scale out the resources; it just changes the allowable limit.
I appraise that the answer is:
Desired capacity
